Does SiriusXM know my listening location?

I am working on a legal paper about copyright. One of the points I am making turns on SiriusXM being unable to tell where a listener is receiving the signal. I think this is true, but I have been having trouble verifying it (or even figuring out how to verify it). I did find a site indicating that SiriusXM radios are strictly receivers, lacking the ability to transmit a signal back to the satellite that would allow this type of geolocation, but I wasn’t entirely convinced of its reliability. Can anybody help me verify that this is true?
